Apple has apparently agreed to a recall of its first-generation Apple iPod nano MP3 players in South Korea after reported cases of the batteries exploding.The Korea Agency for Technology & Standards requested that the iPod nanos be recalled after four reported cases of the devices overheating or exploding, according to the Korea Herald. "Customers who are concerned about possible overheating of the battery can get it exchanged," Park In-kyu, an official with the Korea agency, told the paper.The paper reported that Apple rejected the term "recall," however, but offered to replace the batteries and external shells of the MP3 players.Dow Jones Newswires bureau in Korea also confirmed the official's report. "On July 7th, Apple sent a letter saying it will accept the recommendation made by the Korean Agency for Technology and Standards," the agency said, as reported by the wire.Apple declined to comment to the two news agencies.
